Scientists use iPods, car batteries to build a frog surveillance net | Ars Technica: " Arbimon (Automated Remote Biodiversity Monitoring Network), was created by a team led by Dr. Mitchel Aide and Dr. Carlos Corrada-Bravo of the University of Puerto Rico. As described in a paper published by the team in PeerJ today, Arbimon's monitoring stations use an iPod recording application to capture up to 144 one-minute audio recordings per day of animal calls. Most of the components of the monitoring stations—the iPod, the battery, a voltage converter, a preamplifier for the microphone, and a router—are in a sealed watertight case. A 50-watt solar panel powers the system and charges the battery during the day."

The Big Blob » Moore Neighbor Contour Tracing Algorithm in C++: "This post shows the implementation of Moore’s neighbor tracing algorithm in C++. This algorithm performs what is called contour tracing i.e.
tracing the borders or boundaries of, in this case, a binary image. The two images below illustrates what the algorithm does with a pure black and white/binary image."

Moore neighborhood - Wikipedia, the free encyclopedia: "In cellular automata, the Moore neighborhood comprises the eight cells surrounding a central cell on a two-dimensional square lattice. The neighborhood is named after Edward F. Moore, a pioneer of cellular automata theory. It is one of the two most commonly used neighborhood types, the other one being the 4-cell von Neumann neighborhood. The well known Conway's Game of Life, for example, uses the Moore neighborhood. It is similar to the notion of 8-connected pixels in computer graphics."

Exploring the HTML5 Web Audio: visualizing sound | Smartjava.org: "Create an analyzer node: With this node we get realtime information about the data that is processed. This data we use to determine the signal strength
Create a javascript node: We use this node as a timer to update the volume meters with new information
Connect everything together"

Do Things that Don't Scale: "It's not enough just to do something extraordinary initially. You have to make an extraordinary effort initially. Any strategy that omits the effort—whether it's expecting a big launch to get you users, or a big partner—is ipso facto suspect."

Magnolia - Wikipedia, the free encyclopedia: "Magnolia is a large genus of about 210[1] flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol."
